sennheiser, audio technica, lectrosonics, sony...they all make units but they're all around the same price except for Lectro. Much more money.
Sennheiser and AT1800 single channel are about the same money and equal in quality.

Be aware that changes in use of radio frequency spectrum rules due to take effect this month (part of the Digital TV conversion) will result in some frequencies previously used for wireless mics (i.e., the "700 mHz" bands) being used by other communications services. While the reputable US sources no longer sell microphones on these channels, you may be able to find microphones configured for these bands at fire sale prices, possibly being unloaded by current owners. How much of a problem this will be I do not know, but it is something to watch out.

Also be aware that "Legal Frequencies" in the USA are different to those in the UK & EU, so purchase equipment manufactured for use in the UK market.

That's a good point, in fact despite the cheaper prices in the USA I have been caught a couple of times with warranty issues and other such things when buying direct from the states so when I am shopping around these days I tend to go for the EU & home market.

I've been using Sens at work, and Samson Micro's. I prefer the micros (airline)
They work, offer use of mic on the sender itself and have phantom power built in to power a number of other mics available for the unit. At 300 bucks you can't go wrong.

While I don't knowing the legalities of importing and using such gear, you can look up the frequencies available in the area you plan to work at : Find Available Frequencies and see if the freqs on your units are compatable with what's there.../Battle Vaughan/miamiherald.com video team

We've been using the Samson Airline wireless lapel mic, transmitter and receiver. It was pretty inexpensive (less than $200 I'm sure) and we've been very happy with it. Of course, we'll probably step up into something better later. But this works for now.
